1. Smudge cells percentage on blood smear is a reliable prognostic marker in chronic lymphocytic leukemia
Abstract Objective We evaluated the relevance of using the smudge cell percentage in the blood smear as a prognostic marker in CLL. Methods In this prospective study, 42 untreated Senegalese patients with CLL were enrolled. The diagnosis was established, based on the peripheral blood count and flow cytometry using the Matutes score. Cytogenetic aberrations

2. When karyotype is decisive for myelodysplastic syndromes diagnosis
ABSTRACT Introduction: The myelodysplastic syndromes (MDS) are a group of heterogeneous clonal hematopoietic stem cell disorders that results in peripheral blood (PB) cytopenias and bone marrow (BM) dysplasia. Dysplasia is the hallmark of the disorder, and must exceed the threshold of 10%. Conventional karyotype (KT) has a role in the classification and pro

3. Quebra espontânea de cromátides como evolução clonal em pacientes com síndrome mielodisplásica
RESUMO A síndrome mielodisplásica (SMD) é uma desordem clonal das células-tronco hematopoiéticas caracterizada por citopenias periféricas devido à hematopoiese ineficaz e pelo aumento do risco de evolução para a leucemia mieloide aguda (LMA). As alterações cromossômicas representam o marcador mais importante da estratificação de risco para a tr

4. Carcinoma ex-adenoma pleomórfico derivado de adenoma pleomórfico recorrente mostra diferença importante por array CGH em comparação com adenoma pleomórfico recorrente sem transformação maligna
Resumo Introdução: Uma etapa fundamental do desenvolvimento do câncer é o acúmulo progressivo de alterações genômicas, resultando na ruptura de vários mecanismos biológicos. Carcinoma ex-adenoma pleomórfico (CXAP) é uma neoplasia agressiva que surge a partir de um adenoma pleomórfico. O CXAP derivado de um AP recorrente (APR) foi raramente rela

5. Investigation of the GJB6 Deletion Mutations Del (GJB6-D13s1830) and Del (GJB6-D13s1854) in Iranian Patients with Autosomal-Recessive Non-Syndromic Hearing Loss (ARNSHL)
Hearing loss (HL) is the most common inherited sensory disorder affecting about 1 in 1000 births. The first locus for nonsyndromic autosomal recessive HL is on chromosome 13q11-22. The two genes, GJB2 and GJB6, are closely located on chromosome and are known to be co-expressed in the embryonic cochlea. Deletion mutations involving GJB6 were associated with a

6. Genetic aberrations in multiple myeloma characterized by cIg-FISH: a Brazilian context
Genetic abnormalities are critical prognostic factors for patients diagnosed with multiple myeloma (MM). This retrospective, multicenter study aimed to contribute with the genetic and clinical characterization of MM patients in a country with continental dimensions such as Brazil. Genetic abnormalities were assessed by cIg-fluorescent in situ hybridization (

7. The complex translocation (9;14;14) involving IGH and CEBPE genes suggests a new subgroup in B-lineage acute lymphoblastic leukemia
Abstract Many subtypes of acute lymphoblastic leukemia (ALL) are associated with specific chromosomal rearrangements. The complex translocation t(9;14;14), a variant of the translocation (14;14)(q11;q32), is a rare but recurrent chromosomal abnormality involving the immunoglobulin heavy-chain (IGH) and CCAAT enhancer-binding protein (CEBPE) genes in B-lineag

8. OMNIS HOMO DE NECESSITATE EST ANIMAL: SIGNIFICACIÓN Y REFERENCIA VACÍA EN LA SEGUNDA MITAD DEL SIGLO 13
The question 'whether an utterance (word/term/name) loses its signification with the destruction of things (i.e. things signified)' is raised as a question about the truth-value of assertions with an empty term as a subject, namely as a sub-problem of the sophism 'Whether "omnis homo de necessitate est animal" is true when no man exists (=OHNEA)'. In this pa

9. Screening of Connexin 26 in Nonsyndromic Hearing Loss
Introduction The first locus for nonsyndromic autosomal recessive hearing loss is on chromosome 13q11-22. The 35delGmutation is present in 80% of cases in which GJB2 is involved, which makes the study of this mutation very important. The viability and benefits of screening for mutations in the connexin 26 gene are now beginning to chan

10. Evaluation of chromosomal abnormalities by cIg-FISH and association with proliferative and apoptotic indexes in multiple myeloma
Eighty-six newly diagnosed multiple myeloma (MM) patients from a public hospital of São Paulo (Brazil) were evaluated by cIg-FISH for the presence of del(13)(q14), t(4;14)(p16.3;q32) and del(17)(p13). These abnormalities were observed in 46.5, 9.3, and 7.0% of the patients, respectively. In order to identify the possible role of del(13)(q14) in the physiopa

11. Anormalidades citogenéticas e sua relação com a proliferação e a apoptose celular em portadores de mieloma múltiplo / Cytogenetic abnormalities and their relation to cell proliferation and apoptosis in multiple myeloma patients
Anormalidades citogenéticas recorrentes são encontradas nas células tumorais de portadores de mieloma múltiplo. No momento do diagnóstico a t(4;14)(p16;q32) e a del(17p13) ocorrem em 10-20% e 5-10% dos casos, respectivamente, e são associadas à evolução clínica desfavorável. A del(13q14), por sua vez, ocorre em cerca de metade dos pacientes, poré

12. Leucodistrofia metacromática : caracterização epidemiológica, bioquímica e clínica de pacientes brasileiros
Introdução: A leucodistrofia metacromática (LDM) é um EIM, do grupo das doenças lisossômicas (DL) de herança autossômica recessiva, causado pela atividade deficiente de arilsulfatase A (ARSA), uma enzima lisossômica envolvida na degradação de glicolipídeos sulfatados. O gene ARSA em humanos está localizado no cromossomo 22q13. Dados epidemiológ
